Q:
We believe that we are seeing Satellites orbiting as we are
stargazing. How can we know which satellites they are? How can
we get information on the orbits of satellites, i.e. whether
they move east to west or whatever?

A:
Refer to http://chandra.harvard.edu/about/tracking.html
, a special article on tracking Chandra using MSFC's J-Track
3D--an exciting, three dimensional version of their real-time
tracking software (java enhanced). You may also view other
crafts, such as the Space Station, various satellites, shuttle,
etc.
